okay, so i know i have a problem, clearly, i mean i eat 170 calories a day or less. i'm 17, 5'7-8 and i weigh 94 pounds. i realize i'm underweight. And i don't even know exactly why i keep doing this to myself, i'm so weak and tired and anti-social and i've been in denial for so long but i know i need help now, but i'm too scared to talk to my mom about it. And whats worse, i'm more scared of gaining weight back or becoming overweight if i were to start eating more. Also i have a history with bulimia, so just makes matters worse. i have no idea what i should do, i know i've taken the first step in realizing i have a problem, but i just don't know if i can handle doing anything about it. i really need some advice, thanks!!
